Title: Binarization circuit for optical disk device
Inventor: SHIMIZU AKIHIKO
IPC: G11B7/005
Filed: 1989-04-27
Abstract: PURPOSE:To read the information stored in an optical disk without fail and to enable acquisition of synchronism in the short time by loading DC feedback to a comparator after AC coupling processing is completely followed up. CONSTITUTION:Until an AC coupling circuit 1 completely follows up an analog signal, a switching means selects a fixed binarization threshold level set in advance under the control of a delay circuit 7 and comparison processing for binarization is executed in a comparator 3 by using this level. After the AC coupling circuit 1 completely follows up the analog signal, operation is switched to the binarization threshold level by a DC feedback circuit 5 and the DC feed back is loaded. Accordingly, after AC coupling processing in the AC coupling circuit 1, the deviation of a bit duty ratio does not lead the deviation of the bit duty ratio in the DC feedback circuit 5 and after binarization, the deviation of the bit duty ratio is prevented. Thus, a signal is read without fail and the acquisition of synchronism can be executed in the short time.

Title: Flash memory controller, flash memory control method and storage medium storing program readable by computer
Inventor: SAWANO YASUAKI
IPC: G11C16/02
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To surely prevent erroneous write to a data write area by simple constitution by judging the matching state of data written to the data non- written area of a flash memory and the data read from the data non-written area and judging the packaging defect of the flash memory. SOLUTION: A control circuit 1 judges whether or not the flash memory is packaged. In the case of judging that the flash memory is packaged, the control circuit l writes the data to the data non-written area of the flash memory. The control circuit 1 reads the data written to the data non-written area of the flash memory and judges whether or not they match with prescribed data. Since the data write of the flash memory is controlled based on the judged result, erroneous data write accompanying the packaging defect of the extended flash memory is inhibited and the data loss of the flash memory accompanying data write is prevented.

IPC: H04R3/00
Filed: 1982-06-24
Abstract: PURPOSE:To realize stereophonic and monaural combinational use by using double winding consisting of a group A and a group B and putting the L and R outputs of the group A antiphase with the L and R outputs of the group B. CONSTITUTION:Winding B1 and winding A1, and winding B2 and winding A2 are coupled mutually preferably as close as possible, so the so-called bifilar winding is ideal, but up and down superimposing winding or left and right line winding may be employed as far as necessary coupling within an in-use frequency range is obtained. The winding B1 and winding B2 are connected in antiphase relation with the A-winding side and the L and R outputs are synthesized in phase to obtain a vertical oscillation output. In this case, horizontal leakage to the vertical output side is <-30dB and only a stylus noise is obtained, so this is added to a main signal in antiphase relation to cancele the noise. A double variable resistor VR is used to find the best phase and intensity of a cancelling output.
